How Often Should Antifreeze Be Added to a New Car?

[LaAthena]

For vehicles with short operating times, it can be replaced every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-lasting antifreeze can remain effective for up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are found in the antifreeze, it should be replaced promptly, and the system should be cleaned. Types of Antifreeze: Antifreeze is generally categorized into three types: ethanol-water type, glycerol-water type, and ethylene glycol-water type. How to Choose Antifreeze: The basic indicators of antifreeze are its freezing point and boiling point. On the market, antifreeze comes in specifications with freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose one with a freezing point at least 10°C lower than the lowest temperature in your region. Methods to Determine If Antifreeze Is Low: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to low antifreeze levels, though it could also be caused by excessively high temperatures inside the cylinder. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving; add antifreeze promptly. Check the water level marks on the antifreeze tank. The normal antifreeze level should be between the maximum and minimum marks. To determine if antifreeze is low, observe the marks. If the antifreeze level is below the minimum mark, it indicates a shortage of antifreeze.
